The use of mathematically rigorous optimization methods plays a key role in transitioning the HVAC&R industry from refrigerants with high global warming potential (GWP) to those with lower- GWP and lower environmental impact. The transition requires re-design of components such as heat exchangers and compressors as well as system architectures. This session presents application of optimization methods for heat exchanger and heat pump system design. Also discussed are specific refrigerant blends such as the R454-series and the system modifications required to transition from R410A to its lower-GWP alternatives.
